The Comprehensive Thyroid Assessment is a hormonal test which reveals imbalances that often go undetected with more limited assessments. This thyroid hormone testing measures:

• Unbound levels of T4 and T3 which reflect the bioactive portion of thyroid hormone.  This hormone assessment can identify not only overt hyper-and hypothyroidism, but subtle sub-clinical manifestations of thyroid dysfunction.

• Reverse T3, levels of which can increase when peripheral conversion to T4 to active T3 is impaired.  Peripheral thyroid imbalances may arise from nutrient shortages, heavy metal exposure, adrenal stress, enzyme deficiencies, and other chronic illness.

• Thyroid antibody levels, which help gauge autoimmune response and may reflect metabolic irregularities and hypothyroidism even when TSH and T4 levels appear normal.  Thyroid antibody levels may rise in response to trauma, dysbiosis, inflammation (including thyroiditis) or progressive thyroid degeneration.
